Figure 1
Plain radiograph of the right hip showing a mature periosteal reaction along the posteromedial proximal femoral diaphysis (arrow), without any fracture identified.
Figure 2
a) Right proximal femur MRI: axial T2-weighted inversion recovery (IR) image shows high signal intensity at the insertion site of right adductors muscles (arrow), extending around the diaphysis as a circumferential ring (arrowheads). b) Right proximal femur MRI: sagittal STIR image shows high signal intensity interesting the posterior soft tissue, and the bone marrow (arrowheads) with a linear low signal component interesting the medial cortical bone of the femoral shaft (arrow), consistent with stress fracture.
Figure 3
a) Coronal CT maximum intensity projection reconstruction of the proximal femur shows medial periosteal thickening and fine line of lucency consistent with stress fracture (arrows). b) Axial CT image of the proximal femur shows the medial stress fracture (arrow) with a periosteal reaction on its posteromedial part (site of adductor’s avulsion) (arrowhead).
